A 48 h exposure of Scenedesmus sp. to sublethal concentrations of Cu (2.5 and 10 microM) and Zn (5 and 25 microM) caused a concentration-dependent inhibition of growth, photosynthesis, respiration, NO(3)(-) uptake, and nitrate reductase (EC 1.6.6.1)

Azolla pinnata and Spirodela polyrhiza showed profound ability to take up Cd from ambient medium. Cd adsorption by test plants occurred rapidly during the initial stage of incubation, but the process slowed down and reached an equilibrium in 120 min.

Effects of light and temperature, the most important variables in natural environments, on the toxicity of Assam crude oil extract were examined. Illumination of oil extract increased the degree of inhibition of growth, photosynthesis, and respiratio

Effects of pH, temperature, EDTA and photosynthetically available radiation on the uptake and toxicity of Cd was investigated in Spirodela polyrhiza (L.) Schleid. and Azolla pinnata R. Br. In general, Cd toxicity was accentuated in conditions which f

A. pinnata showed a remarkable ability of taking up Cd from the external medium. Of the total Cd taken up by the test plant, surface adsorption was about 90%. Cd adsorption did not occur at a constant rate, however, an equilibrium was reached in 2 h.
